[Purposes] The relocation of poverty alleviation has fundamentally cured the persistent poverty in the villages of Linxiang District under the difficult living environment and working methods of "high mountains, longitudinal valleys, mountainous settlements and vertical farming". However, the drastic changes in the environment and the relationship between people and the environment have objectively led to the phenomenon of maladaptation and mismatch in the multiple relationships between people and the environment and demand and supply. Scientific examination of the habitability of the human environment in relocation sites for poverty alleviation and relocation, as well as the suitability of the subject and object elements, can provide optimized policy and technical guidance for their subsequent development. [Methods] Based on field research, sample survey and household interview data of 35 centralized relocation settlements in Linxiang District, the study explores the internal logic of habitat adaptability of the relocation sites for poverty alleviation from the perspective of subjective and objective comparison.This study compares and analyzes the suitability of the settlement habitat construction by constructing a subjective and objective evaluation model of "satisfaction of relocated villagers" and "level of habitat construction". [Findings] The study shows that there is a difference in the adaptation of human living environment construction in different dimensions in the relocation site of Linxiang District, i.e., the physical facilities environment and social and humanistic environment are in a "reasonable" adaptation state, the natural ecological environment is in a "super supply mismatch" mismatch state, and the economic development environment is in a "under supply mismatch" state.In order to make the living environment reach the ideal state of adaptation, each resettlement site must adopt the optimization strategy of "maintaining the balance and improving the whole" for the state of adaptation and "key breakthrough and reasonable deployment" for the state of mismatch. [Conclusions] Based on the limited nature of "adaptability" and the partial waste of resources or insufficient development support implied by the mismatch, we analyzed the effectiveness and adaptability of habitat construction and explore optimization strategies. This helps to completely eliminate the hidden environmental stumbling blocks to the development of rural revitalization in the relocation sites, and stabilize and fully optimize the overall social, economic, cultural and ecological development pattern of the relocation sites as soon as possible.
